Four Years of Glide Avalanche Monitoring at Olmsted Point, Yosemite National Park

Co-author(s): Sue Burak; Steven Pestana; Jessica Lundquist

Four years of time lapse camera monitoring of Olmsted Point in Yosemite National Park are presented, allowing full characterization of the avalanche activity throughout the winter and spring. Results show a majority of the avalanches are glide avalanches, with at least one potentially destructive avalanche hitting the road every year. The remote location and wilderness restrictions present unique challenges for forecasting. We conclude by discussing use of other remote tools and future plans.
